LOGOMOT'IVE SAND-BOX.

Specification of Letters Patent.

Patented Apr. a, rain.

Application filed May 14, 1913. Serial No. 767,688.

To all whom it may concern Be it known that I, HARRY Inornn, a subject of the King of England, residing at Altoona, in the county of Blair and State of Pennsylvania, have invented certain new and useful Improvements in Locomotive Sand-Boxes, of which the following is a specification.

This invention relates to the subject of sand boxes, and the primary object is to provide a new and novel means for holding the sand, to be discharged through the pipes to the rail, together with improved means for discharging the same.

To this end the present invention contemplates a sand receptacle having a discharge opening cast integral therewith, the opening through which the sand is discharged being normally closed with sand.

Another object of the invention is to provide means for stirring the sand in the re ceptacle, before it is discharged through the discharge passage to the rails.

A further object of this invention is to provide means for placing and removing the nozzle, as well as to clean the sand-passage of any foreign matter that may be therein.

With these and many other objects in view, which will be more readily apparent, as the nature of the invention is better understood, the same consists of the novel combination and arrangement of parts, as will be hereinafter fully illustrated, described and pointed out in the appended claims.

This invention is quite susceptible to a wide range of structural modification without departing from the spirit or scope of the invention, but a preferred and thoroughly practical embodiment of the same is shown in the accompanying drawings, in which;

Figure 1, is a cross sectional View of my improved sand box. Fig. 2, is a plan view of the parts shown in Fig. 1. Fig. 3, shows the manner of constructing the seat for cleaning cap. Fig. 4 shows the cleaning cap applied, and illustrates the neat appearance of the various parts assembled.

Similar numerals refer to similar parts throughout the several figures of the drawings.

In carrying out this invention, 1 construct a sand box, designated by the numeral 10,

with a plurality of downwardly inclined converging surfaces 11 and 12.

The surface 12 is preferably cut out form ing an outlet pocket 18, into which the sand is deposited as it rolls down the downwardly inclined converging surfaces 11 and 12. At the bottom of the surface 11, there is provided a ledge 14, through which protrudes a nozzle 15, which is adapted to be screwed into the threaded blast pipe opening 16 in the ledge.

The ledge 1a is further provided with an air jet port or passage 17 through which air passes to stir the sand in the ocket 13. The nozzle 15 is positioned in dlrect alinement with a main discharge opening 18, which is inclined upwardly, parallel to the surface 12; this inclined surface serving as a gate for the sand, which is effectively held against gravity discharge. Since the surface 19 is above the point 20 in the pocket 13, the sand cannot flow except when it is driven up the inclined passage by a jet of air issuing from the nozzle 15. It will be observed that ad acent the upper end portion 19 of the angularly disposed discharge opening 18, a downwardly disposed delivery neck or port is in communication therewith for the delivery of the sand through the conducting pipe 22. Since the air will necessarily give the sand a velocity sufficient to be forced up the incline, it is obvious that a movable impinging plate 21 should be provided which can readily be renewed when, through long service, the same has become worn.

The pipes 22 leading from the sand box to the rail are of the usual size and type, as well as the air inlet pipes 23, and to this part of the mechanism I make no claim, but

What I claim as new and desire to be secured by Letters Patent is,

1. A sand box including a base provided with an angularly disposed main discharge opening, a downwardly disposed delivery port at the upper end of said discharge opening, an outlet pocket opening laterally into the lower end of said main discharge opening, a blast pipe opening in communication with said main discharge opening, and an air jet port extending through the base of said outlet pocket and in communication with said blast pipe opening.

7 opening, a downwardly disposed delivery.

2. A sand box including a base provided wlth an angularly disposed maln discharge port communicating with the upper end of the main discharge opening, a detachable impinging plate covering the upper end of the main discharge opening, a blast pipe opening communicating With the lower end of the main discharge opening, and an outlet pocket opening laterally into the main discharge opening and also having a ported communication with the blast pipe opening,
